DETAQHABLE AUTOMQBILE SPRING-TIRE; f

To all whom 'it'may. concern:

Be it known thatl, Linens LA BAUVE,

a citizen of the United States, residing at Houston, in the county ofHarris and State of Texas, have invented certainnew and usefulImprovements in Detachable Automobile Spring-Tires, of "which. thefollowing is aspecification. a

' This invention relates tocertain new and V useful improvements in adetachable automobile-spring tire and particularly to a detachableautomobile tire embodying leaf springs, an object being to design andconstruct the tire so as to fit, without alteration, 1 5. wheels madefor pneumatic tires.

Among further objects; the invention .seeks to. provide a simpleconstruction and arrangementrof leafsprings in whichthe al- 'ternatesprings have 'a secureconnection With the inner and outer tire parts,respec :tively, such connections facilitating the as sembling of theparts. 1 r i The invention further resides in thefeaturesof-construction and the arran einents and combinationsjof parts'hereina er described and claimed, reference being had to --theaccompanying drawings wherein- Figure l :is a. side view'withthe lowersec- ;tion of the outer casing removed the inner casing beingpartly-broken away and partly in section; z. p

outer casing 12 is :also. preferably aconstructed of steeland is round.in section with the exception that its free edge portions are extendedinwardly in parallelism :to pro- .vide rim-embracing flanges 13. An'elastic cover 14, such as rubber, is appliedatoi and secured on theouter easing. Y I x The outer casing is yieldably and resilientlysupported from the v rimimember by .ntwo sets of bowed leaf springs, theleaf springs '15-'being bowed inwardly and secured centrally to the rimwhile the leaf springs l6yare bowed-outwardly and are secured centrallyto the outer casing.,' The springs of the twov sets are alternatelyarranged sov that one leaf spring is bowedoppositely .to the nextadjacent fleaf springs. The endszof. each spring are p'ivotally andswingingly connected to the opposing ends of the two adjacent springs bydouble, short links 17 sothat theends of eachleafispring V. aresupported in suspension from the ad- -.1j acentends ofthe leaf springsonthe oppositesides thereof. 7 i. The springs 15 have their-centralconvex portions seating on the lugslS which are arranged in a peripheralseries-betweenthe side walls of the channeled :rim, eachspring 15.being: secured to its seat bya transverse cleat .19 and a, pair OfC2Lp'SCI'eWS .20, the latter "passing through the .endportions of thecleat and'havingthreaded engagement With the lugs and rim, as depictedin Fig.,10.

The ends of the cleats fitsnuglyfbetween the ,sides-of the channel rimand have; extensions 21 that engage over thgeinner edges "of said sides.vA rivet .22 securesthe cleat cen trally t0 the spring :15, passing'through the .several leaves of the latter and headedrto engage in .arecess 23,.forme'd in the outer [face of the lug .18, .and thereby serveas a means for'holding hesp ringagainst longitudinal slipping Themountingfor the springs .16 includes .a peripheral series of U-shapedor. channeled brackets. or supports 24 that have their outer.

faces convexedto conform tothe'inner; sur- ,:face of the outericasingtowhich they are z ffil mly secured; The. leavesofeach springlfi arealsoriveted together, and the outer head of the rivet is seated in a recess25, formed in he b se .Q ihe :Us aped-supp 2e to withstand longitudinalstress. The inner end of the rivet is embedded in the transverse bearingplate 26 and both are channeled crosswise to receive a transverse pin27, the end portions of which are extended through the sides of theU-support and the sides of the outer casing, as depicted in Fig. 9. Theends of the pin may then be riveted, being accessible through suitableregistering openings 28 left in the rubber covering 14.

means of a pair of books 29 and cooperating slotted keepers 30. Eachhook is riveted to one end of each casing section at a :point spacedinwardly from the abutting ends of said sections, with the shank portionof the hook spaced from the inner walls of the casing for ready yieldingmovement. The cooperating keeper 30 is carried by theabutting end of thecompanion casing section and is provided with an oblong slot 31 throughwhich the hook passes.

Extending beyond the end of the section the keeper is formed with adowel part 32 designed to enter the opposing end of the companionsection and thus aline the sections when being moved together as well asserve to hold the sections in the same plane and reinforce the joint.

To unlock the section, a hole 33 is formed in the rim member oppositeeach keeper of the outer casing to permit a tool being insertedtherethrough for pushing the hook outwardly from engagement with thekeeper.

The tire comprising its inner casings and the included springs, is sodesigned and constructed that it will fit the modern wheels made forpneumatic tire equipment, no alteration being necessary to substitutethe present invention for the pneumatic tire. The tire is punctureproof, resilient and wear-resisting, and the construction is simple anddurable. 1

What is claimed is:

1. A detachable spring tire comprising a rim, an encircling casingformed in sections and. having inwardly extending flange portionsslidably embracing, the sides of the rim, spring means yieldablysupporting the casing from the rim, and means connecting the ends of thecasing sections together in cluding a hook secured within one sectionextending circumferentially and concentrically therewith beyond the endthereof,'and a keeper carried by the adjacent end of the next casingsection and extending beyond said section and being formed to receiveand guide the free end of the hook for holding the sections alined, anda wall at the inner end of the keeper formed with an ing across themeeting ends of the casing sections.

to the casing springs with the outer heads of the rivets engaged in arecess formed in the respective supports,thertransverse plates andembedded rivet heads being channeled crosswise in alinement with theperforations in the sides of the u-supports,

securing pins engaged in thelchannels of the plates and rivets andpassed through the perforations of the U-supports and the sides of theouter casing, and links connecting the ends of the-casing springs to theends of the rim springs. I

3. A tire for automobiles comprising a channeled rim, leaf springssecured on the rim, an outer casing, a series of U-supports extendinginwardly within the casing in spaced relation to the sides of saidcasing,

leaf springs arranged on the supports between their sides, meanssecuring the second springs to the U-supports and reinforcing the sidesof the latter from the" casing.

l. A t1re for automob les comprislng a rim, an outerhollow casing formedin sections, a hook secured at one end within an end of one casingsectlo'n, said hook belng' offset adjacent its point of mounting andextending in spaced relation to the inner wall of said section beyondthe end thereof, the free end of the hook being formed into a 'catchpart, and a keeper carried within" the adjacent end of thevadjacentcasing sec tion, said keeper consisting of a hood-like dowel partprojecting beyond its support ing casing section for alining thesections and for guiding the hook to 1ts keeper, and

a radially extending endwall at the inner end of the dowel part formedwith an opening to receive the hook, said keeper and hook being spacedoutwardly beyond therim LILLIE w. L-ABAUvE.
